To fly for money yes you need Private, Instrument, and Commercial. At the very least...

I can't make the decision for you, but I would strongly recommend flight training through one of the FBOs at one of the airports in the Valley. Start looking up the different airports and figuring out pricing for different flight schools. Call them up, see what they are about, etc. You can do this for NAU, UofA, really any college you're interested in going to. Use Google Maps to find the local airport, then Google the airport and see if any of the businesses on the airport offer flight training.

As for wanting to be ATC. It's kind of a worthless major. Basically they teach you what the FAA would teach you, they hand you a degree, and say good luck with a job. You have a bit of an edge on the people that are just applying normally but if they do hire you, you still have to go to Oklahoma City and receive the same training the hires off the street are receiving. It's a damn easy major. I swear those guys have way too much free time. Kind of a waste of money. In my opinion.

Don't even get me started on the CRJ simulators...What a waste that is. You spend so much more just to receive extra "training" in a CRJ. It's a class that you go over all the systems, all the books, etc etc. And you don't even get a Type Rating. Which means if you go fly for someone that does have CRJs, what you learned at ASU doesn't apply towards your TR. You may be ahead of the curve but you still have to go through the airlines version of CRJ training. It's a huge scheme to suck you dry of money! I swear I can't believe people buy into it...

MPD also just opened up their flight training to non "Professional Flight" Majors. Meaning if you are a communications major you can go to MPD and get your PPL and your INS rating, but not your Commercial that I am aware. But you all ready know my opinion on MPD training...
